To Determine the wind direction and strength is a pretty standard task in meteorology. From these parameters based on perceived air temperature, as well as the weather itself - because the winds carry a significant air mass. From the leading of the weather you can often hear that somewhere there are large cyclones or anticyclones of the Arctic or, for example, on the Atlantic side. Wind is the movement of air masses in the lower atmosphere from a region of high to low pressure, so that strong differences of pressure in close areas depends on the wind force. That is why hurricanes and typhoons rarely occur in the heart of the continent. But close to the sea or ocean are much more common. Calm, is calm, is observed, where the pressure in the related fields the same way. But this situation is not very frequent.

prevailing wind directionTo Determine the prevailing wind direction, and especially the speed and strength of gusts, it is very important for air traffic controllers. In strong winds the pilot will need to do on this amendment, but if the wind is too strong, might even have to cancel or postpone the flight. Same thing with ships. Even on the boat strength and wind direction are important. That's why meteorologists record the speed and direction of winds with the help of special instruments, and then even make up a special schedule, a wind rose, illustrating the wind which direction is predominant in a particular place. Usually wind rose compiled at the end of the year or even longer period. For example, the prevailing wind direction in Moscow in recent years - the South-West. That is, most of the time in a year it blows South-West or West wind.

wind directionBy the Way, when talking about the direction of the wind, marking the cardinal directions is of particular importance. If the wind saying that he's southern, so it comes from the South. So, some confusion arises when people see the direction of the arrow from left to right and think that the East wind. There is no mistake! In determining winds the arrows always indicate the direction from which the wind is blowing, but not much. Why is it fixed, is difficult to say, so it happened.

So how do you determine wind direction? Easy! Mankind has invented several devices which can do this quickly: wind instruments used on ships, weather vane, which helps to determine the direction and strength of the wind even in everyday life, as well as special pointers of wind, which can often be seen in airports: they are made in the form of long orange-and-white semblance of a net.

wind direction in MoscowThe force of the wind, usually determined together with its direction, often denoted in scores or meters per second. Sometimes, when exact figures are unimportant, the terms used are "moderate", "weak" and so on.

In Addition, there are seasonal winds, as well as those the direction of which depends on the time of day - usually observed on the coasts of the seas or other large bodies of water. We are talking about breezes and monsoons. They have a serious impact on the climate and weather in cities and settlements located not only near large bodies of water, but in the heart of the continent.

Thus, the wind direction and strength is one of the basic weather and climatic factors along with temperature, pressure and precipitation.
